SOCKET-SWITCH.

Specification of Letters Patent.

Patented Sept. 3, 1912.

To all whom it may concern:

Be it known that I, WILBUR G. Pnm, a citizen of the United States,residing at Bridgeport, county of Fairfield, State of Connecticut, haveinvented an Improvement in Socket-Switches, of which the following is aspecification.

This invention relates to electrical socket switches and has for itsobjects to simplify, cheapen and to generally improve their constructionand mode of operation.

With these objects in view I have devised the novel socket switch whichI.will now describe, referring to the accompan ing draw ing forming apart of this speci cation and using reference characters to indicate theseveral parts.

Figure 1 is a view partly in elevat on and partly in vertical sectionillustrating the construction of my novel switch; F1 2 a plan view ofthe lower insulating bloc and the switch mechanism, the brackets beingin section and the returning spring removed; Fig. 8 a' similar view-withthe operating member and the hook removed; Fig. 4 an edge view of theoperating member; Fig. 5 an inverted plan view of the operating member;Fig. 6 a pe ective of the contact; Fig. 7 a perspective of the retainer;Fi 8 a plan view of the blade; Fig. 9 an on view corresponding with Fig.8 Figs. 10, 11 and 12 plan views correspondin -W1l3b Fig. 2, thecontact'and retainer and t e returning spring being removed, showingdifg airts in the'operation of the switch, and g. 18 is'a section on theline 18-18 in Fig. 8 looking in the direction of the arrows.

Motion in "any" suitable manner with bracket 28.- Bracket 29' ia''ele'ctricall connected to the scrcwfishellby 'a screw 8 which assesthrough tho==1ower insul'ating bloc and which parts may be of anyordinary or preferred construction." The insulating blocksare spacedapart and retained in o erative positronbycurrenfl; carrvingbrac ets 28and 29, each of which ,1 means for'hol rigidly secures both the screwshell and the bracket thereto.

Important features of my novel switch are an insulating operating member33, an oscillating blade 34 and a blade retainer 35.

86 denotes the center screw with which the center contact of a lamp (notshown) makes electrical connection. In the present instance I have shownthe center screw as passing through the shank of the retainer and theseveral parts as retained 1n place by a nut 37. It is unim ortant,however. how the retainer is secure in place, as it is not in thecircuit. The upper end of the center screw is unthreaded and forms apivot on which the blade and the o erating member oscillate. The bladeis s own as resting upon the nut and the insulatin operating member asprovided with a s save 38 which rests upon the blade. The operatingmember is actuated by means of a two-armed hook 39 to which theoperating chain is connected and is provided with shoulders 49, for apurpose presently to explained, and with shoulders which enage thebrackets (see Figs. 10 and 12) to imit the oscillation of said member ineither direction. A s ring 40, one end of which is connected to t e hookand the other to a stud or screw 41, acts to return the hook to itsnormal position after each actuation. The operatinn member is providedon its upper side with pins 42 (shown in the present instance asconnected and forming a yoke) which are adapted -to be engaged by thearms of the hook respectively to actuate the switch (see Figs. 10, 11and 12). Upon the underside-of the operating member is a two-armedspring 48 which is retained in place by a'screw or stud 44 passingthrough itheEcoil and-the arms of which lie on oppo- Fsite sides ofsleeve 38 and engage the opposite sides of a pin 45 projectin from the'blade. This pm is also engage by shoul- 1 ders149 upon the operatingmember to disenggge the blade from the contact' and the retainer,as'will be more fully explained.

ETheablade is'preferably provided inits up- 30 denotes a'contact h vingelectricalcon' ;per andlunder sides with coves 46. The preferred form ofthe con act and'retainer will bereadily understood from Fi 6 and i'hzrsspectlvelv each bein provi ed with ding the bla e. The contact isshapedto secure as much contact. surface aspossibletviththeblade and isprovided with a rib 47 which is adapted to engage the groovein the uppersicle of-the blade to hold the blade in engagement with the contactuntil it is disengaged therefrom by one of the shoulders on theoperating member. The retainer is provided with a rib 48 which isadapted to engage the roove in the under side of the blade and ho d theblade in engagement with the retainer until it is disen-' gaged by theother shoulder on the operat mg member.

The operation is briefly as follows: Starting with the parts in theosition shown in Figs. 2 and 10, in which he circuit is open and theblade is held by the retainer throu h the frictional engagement of therib on t e retainer with a groove in the blade, a pull upon the chainwill cause one of the arms of the hook to engage the pin 42 on theoperating member toward the left in Fig. 10 and will move the )arts tothe position shown in Fig. 11, in which it will be seen that the arms ofspring 43 have been separated through movement of the operating memberrelative to pin 45 on the blade and the power of the .sprin isaccumulating to throw the blade to t e closin position as soon as theengagement of a s oulder 49 on the operating member with the in on theblade disen ages the blade from t e retainer and the 111 power of thespring acts to swing the blade to the position shown in Fig. 12 in whichit is in engagement with the contact, the contact and retainer, however,being omitted from Figs. 10, 11 and 12 for the sake of clearness ofillustration. The first pull upon the chain therefore, closes thecircuit. The instant the pull upon the chain is released, spring 40returns thehook to its normal position, as in Fig. 12. A second ull uponthe chain will cause the other arm 0 the j hook to engage theother'pin42 on the operating member and open the circuit again; that is,change the parts from the osition shown in Fig. 12 to that shown inig.'-10 The operation is precisely the same in; opening or closing thecircuit. -.Themovement of the o crating member by'mean's of the two--armec hook and chain accumulates power in one arm of the spring untiltheblade is dis-.

engaged by the shoulder on 'the:operating" member from either thecontact or retainer. as may be, after which disengagement the"accumulated power of the spring' quickly sw1ngs=the .b BdG'ufIOm. theclosing to the: opening position .orvice versak- M The passage oi thecurrent willbe readilv understood Tfrbm-Fig. '18 in" connection'k'ivviththe ;other views.
